1. A gas turbine engine comprising:
- a rotor stage;
a variable reluctance rotor without windings or magnets; and
an annular array of stators, each stator configured to function, in conjunction with the variable reluctance rotor, as an electrical machine,wherein the stators are irregularly spaced,wherein each irregularly spaced stator extends along a circumference of the variable reluctance rotor by a different amount than at least one stator adjacent to the each stator, andwherein the variable reluctance rotor is integral with or mounted to the radial periphery of the rotor stage.
